The Interlagos round of the World Endurance Championship has been moved from its August date to become the series finale at the end of November.

The Brazilian event, originally lined up for August 31, has been rescheduled as a result of a request from promoter Emerson Fittipaldi and will now take place on November 30, two weeks after the Bahrain round.

Two reasons have been given for the request: a desire to have longer to promote the event after the end of the FIFA World Cup in Brazil in June and July; and a shift in the date of the Brazilian Grand Prix at Interlagos to November 9.

This meant the August date was unavailable because the circuit has to be prepared for the arrival of Formula 1.

The move means that there is now a gap of more than three months between round three of the WEC, the Le Mans 24 Hours on June 14/15, and the start of the non-European leg of the championship at Austin in the USA on September 20.

Series organiser the Automobile Club de l'Ouest has reached an agreement for its race to be held on the Saturday of the joint promotion with the United SportsCar Championship at Austin.
